Mariah Carey has more to look forward to than becoming a mother. The songstress, who is launching a footwear line with HSN this month, is trying to make room for her ever-growing shoe collection. Carey dished to Insider that her closets in New York and Los Angeles, which have been showcased on MTV’s “Cribs,” are filled with her most treasured pairs (including a variety of YSL, Chanel and Christian Louboutin heels), displayed on glass shelves, while everything else is organized by color and style. “I definitely save my favorites,” she said. But the mother-to-be is trying to make some changes, welcoming more casual styles to her mix of towering stilettos and platform pumps, per hubby Nick Cannon’s suggestion. “My husband brought me all these flats the other day, which were gorgeous, but kind of not comfortable for me,” she said. “I can tolerate a high-heel shoe for hours on end.” And no matter what’s on her feet, Carey (above with Cannon) said welcoming a new member to the family won’t slow her down at all. “It makes me really want [to design] a maternity line.” Tweet
